Both shoes are designed for neutral runners seeking comfort on various terrains. The Ghost 17 holds a bestseller rank of 61, indicating its popularity, whereas the Glycerin 21 ranks lower at 29,881, suggesting it may not be as widely favored.
Design and Aesthetics
The Brooks Women’s Ghost 17 features a stylish combination of white, black, and rose gold, appealing to those looking for both function and flair. In contrast, the Glycerin 21 comes in a sleek black, grey, and white design, catering to a more classic aesthetic. The visual appeal of both shoes is a matter of personal taste, but the bright accents of the Ghost 17 may stand out more during outdoor runs or gym sessions.
Comfort and Cushioning
The Ghost 17 emphasizes soft and dynamic cushioning with its nitrogen-infused DNA Loft v3 technology. It offers an extra 1mm of cushioning in the heel and 3mm in the forefoot, enhancing comfort on long runs. Meanwhile, the Glycerin 21 is designed for those who prioritize supreme softness, boasting even more nitrogen-infused DNA Loft v3 cushioning for a plush experience. While both provide excellent comfort, the Glycerin 21 may appeal more to runners who prefer a softer feel.
Fit and Breathability
The Brooks Women’s Ghost 17 incorporates a double jacquard air mesh upper that ensures breathability and a snug fit, adapting to the foot’s natural movements. The Glycerin 21 enhances this with its internal stretch bootie that surrounds the foot, offering a flexible fit that moves with the runner. While both designs prioritize comfort, the Glycerin 21’s plush internal fit may provide a more luxurious feel during extended wear.
Performance and Stability
When it comes to performance, the Ghost 17 is engineered with flex grooves in the midsole to promote smooth transitions, making it suitable for various activities like road running and cross-training. The Glycerin 21 focuses on stability with a broad platform that supports smooth heel-to-toe transitions, ideal for runners looking for a dependable shoe during intensive workouts. Both shoes excel in their respective areas, but the Glycerin 21 might be the better choice for those seeking stability in their stride.
Durability and Construction
The Ghost 17 features an innovative rubber outsole made with recycled silica, emphasizing durability and responsiveness across different terrains. The Glycerin 21 also boasts a durable construction with its engineered warp knit upper, which is breathable and soft against the foot. Both shoes are built to last, but the Ghost 17’s use of recycled materials may appeal to environmentally-conscious consumers.
Price Comparison
At $110.00, the Ghost 17 is more budget-friendly compared to the Glycerin 21, which retails for $114.95. This price difference of $4.95 represents about a 4% increase in cost for the Glycerin 21, making the Ghost 17 a more economical option for those watching their spending. For runners who prioritize value without sacrificing quality, the Ghost 17 presents a compelling choice.
Which should you buy?
Choosing between the Brooks Women’s Ghost 17 and the Glycerin 21 ultimately depends on your individual needs as a runner. If you are looking for a more affordable option with dynamic cushioning and smooth transitions, the Ghost 17 is an excellent choice. However, if supreme softness and a plush fit are your top priorities, the Glycerin 21 may be worth the slightly higher price. Both shoes deliver exceptional comfort and performance, making them strong contenders in the running shoe market.
